PVSensor for use with film infusion  

The larger PTFE Sensor body is easily attached to the chosen zone by sealing it onto the film allowing it to communicate with the cavity through a minute hole pierced in the film. In use the PVSensor first gives accurate confirmation that full vacuum has been achieved below the film prior to the start of the infusion, it is then able to detect and indicate the small differences in pressure present as the resin passes the sensor point.

With such a system it is now possible to accurately monitor both the low pressures associated with film infusion. - This now leads to the real possibility of employing machinery that will mix on demand and deliver  resin to the delicate film covered mould.
